Unable to get to login page after install

Hello,
I am new to linux. I have installed the ispconfig3 tar file. Went through configuration. When I go to the web interface and type in FQDN:8080 or FQDN:81 in the browser it brings me to the standard index.htm page from /srv/www/htdocs. Does someone know what I need to change to get to the ispconfig login page from the browser?
